Welcome!

Welcome to Zephir, an open source, high-level/domain specific language designed to ease the creation and maintainability of extensions for PHP, with a focus on type and memory safety.

Some features

Zephir’s main features are:

A small taste

The following code registers a class with a method that filters variables, returning their alphabetic characters:

namespace MyLibrary;

/**
 * Filter
 */
class Filter
{
    /**
     * Filters a string, returning its alpha charactersa
     *
     * @param string str
     */
    public function alpha(string str)
    {
        char ch; string filtered = "";

        for ch in str {
           if (ch >= 'a' && ch <= 'z') || (ch >= 'A' && ch <= 'Z') {
              let filtered .= ch;
           }
        }

        return filtered;
    }
}

The class can be used from PHP as follows:

<?php

$filter = new MyLibrary\Filter();
echo $filter->alpha("01he#l.lo?/1"); // prints hello
